This presentation explores additively manufactured metal-matrix composites (MMCs) using Inconel 718 alloy reinforced with titanium carbide (TiC). Through varied single track experiments, we explore melt pool morphologies, defect formation, and microstructural features. Employing analytical predictions and numerical approaches, alongside comprehensive experiments, we aim to understand the printability of these advanced materials.
